Now let me tell you your definite duties in this office and this is your desk . Please sit down .   I see . Thank you . Sir , what kind of duties will I do ?   B , your main duty is to answer phone calls and transfer files to the person who wants them . Is that difficult ?   It's easy . Is there anything I can do for you , sir ?   Well . I have nearly forgotten . Mr Green from ABC Company had an appointment with me , but I will be very busy at that time . If he calls , you can tell him the appointment will be changed to next week .   I will leave a memo for you , sir .
